Keep a look out for Cerastes cerastes. I know they can be found in AZ but you might have to go out of your way to find some. Crotalus scutulatus is anothe beauty that can be found in your state. C. tigris is another beautiful example.

Lol thats always a good idea. tongs.com for all your hot herping needs. I would suggest buying a pinner, large hook, and a venom extractor kit. Thats what I use when I go out for rattlers.
